Snorkeling in New Zealand
Including Abel Tasman National Park (Tonga Island Marine Reserve), Fiordland National Park (Milford Sound), and Goat Island Marine Reserve. On the map.
The vibe
Pulling on a wetsuit here is less about lounging in warm tropical lagoons and more about crisp, temperate waters teeming with kelp forests and darting snapper. Late summer offers the clearest visibility and warmest sea temps, making it the prime window to dip beneath the surface. It is an entirely DIY affair where you grab your own gear, pick a rocky headland, and wade straight off the shore into an unexpectedly vibrant underwater world.
